View Full Version : Idling Problem

06-10-10, 02:17 PM
I have an 07 Ext and my vehicle idles very rough its says its at normal RPM but it feels like it wants to stall out. Brought it to the dealership they said its fine.. My mom has an 08 ext and her idles smooth and sounds much better like her exhuast it louder i dunno if its because its newer or not... My main concern is the idling, I was thinking of getting high end spark plugs but i am not sure that would make a difference! Please help

Take the throttle body off and clean it.The often don't look dirty,but a good cleaning with throttle body cleaner and a rag helps.Drive it around for a few miles so the PCM can relearn the throttle position.Should idle like a champ.Make sure you clean the throttle blade good.Takes about a 1/2 hr and very few tools.Even a caveman could do it!!

How many miles? I would start with a bottle of fuel injector cleaner like Techron in the gas tank, cleaning the t-body as said is another good idea, can be done with carb cleaner.

What kind of plugs would you use? Factory or Bosch Platinum Ir Fusion?

Ac-Delco plugs.They are 8.00 at auto zone

I personally would replace the plugs with that many miles, they say they can go for 100k, but they don't say how they will perform. :)

what are the best plugs that I can get I don't want ac delco, what about those iridium plugs? or the splitfire ones or something like that.. just need some better then OEM suggestions

The Ac-Delco plugs are Iridium plugs.

are those the best plugs to get? And should i make sure the gap is to oem specs before installing them?

Stick with the AC-Delco Iridium; all of my vehicles have them installed (I have a modded L67 3800 car and I run the same plugs as in my LS1 :) and I could not be more pleased -- DO NOT REGAP Iridium plugs - REPEAT - DO NOT ATTEMPT REGAP!
